TLDR
In this article, an iterative nonlinear algorithm for microwave image reconstruction based on moment method solutions to field problems has been suggested, which has been simplified significantly considering the effects due to the dominant nonlinear terms only.Abstract:
An iterative nonlinear algorithm for microwave image reconstruction based on moment method solutions to field problems has been suggested. The algorithm has been simplified significantly considering the effects due to the dominant nonlinear terms only. The results obtained using it have been compared with those reported earlier using a simpler algorithm.read more

Scattering by a dielectric cylinder of arbitrary cross section shape
TL;DR: The theory and equations for the scattering pattern of a dielectric cylinder of arbitrary cross-section shape were developed in this paper, where the harmonic incident wave was assumed to have its electric vector parallel with the axis of the cylinder, and the field intensities were assumed to be independent of distance along the axis.
